Polytrauma Management

Intro & Primary Survey - Life Savers First

Polytrauma: ISS > 15; multiple severe injuries, ≥1 life-threatening. ATLS protocol is key. Primary Survey (ABCDE) & Resuscitation:

• Airway & C-Spine: Assume C-spine injury. Jaw thrust. Oro/nasopharyngeal airway. Intubate: GCS ≤ 8 / compromised airway.
• Breathing & Ventilation: High-flow O₂. Manage life-threatening chest injuries (tension/open pneumothorax, hemothorax).
• Circulation & Hemorrhage: Control bleeding. 2 large-bore IVs (≥16G). Warm crystalloids (RL), blood products.
  • 📌 Lethal Triad: Acidosis, Hypothermia, Coagulopathy. ⚠️
• Disability: Neuro status - GCS, pupils (AVPU).
• Exposure & Environment: Undress. Prevent hypothermia (warm blankets).

⭐ Hypotension in trauma implies hemorrhagic shock until proven otherwise; resuscitate aggressively.

Damage Control Ortho - Fix Fast, Fix Later

• DCO: Staged surgical strategy for critically injured polytrauma patients.
• Prioritizes "life over limb"; aims to minimize the "second hit" inflammatory response from prolonged initial surgery.
• Indications: Hemodynamic instability, coagulopathy, hypothermia (lethal triad), severe thoracic trauma, high Injury Severity Score (ISS >25-40).
• Phase 1 (Fix Fast - Emergency):
  • Rapid, temporary stabilization: External fixation (long bones, pelvis), splinting.
  • Wound debridement, fasciotomy if needed.
  • Goal: Control hemorrhage & contamination, limit surgical insult.
• Phase 2 (Fix Later - Planned):
  • After physiological normalization (typically 24-72 hrs to 5-10 days).
  • Definitive fracture fixation (e.g., ORIF, IM nailing).

⭐ DCO aims to prevent the "second hit" phenomenon, where early major surgery on a physiologically unstable patient worsens outcomes by exacerbating systemic inflammation.

Secondary Survey & Ix - Head-to-Toe Check

• Systematic head-to-toe examination after primary survey & initial resuscitation.
• 📌 AMPLE History: Allergies, Medications, Past medical history, Last meal, Events/Environment.
• Detailed Neurological Exam: GCS, pupils, motor/sensory function.
• Log-roll for spine & back examination.
• Extremities: Deformity, pulses, perfusion, compartment check.
• Investigations (Ix):
  • Trauma series X-rays: Lateral C-spine, AP Chest, AP Pelvis.
  • FAST/eFAST (Focused Assessment with Sonography for Trauma).
  • CT scans (head, C-spine, chest, abdomen/pelvis) as indicated by findings.
  • Baseline bloods: Hb, GXM, U&Es, coagulation profile.

⭐ A missed injury can be life-threatening; the secondary survey aims to identify ALL injuries. Approximately 10-20% of injuries are missed during initial assessment in polytrauma patients.

Scoring & Complications - Numbers & Nightmares

• Scoring Systems:

  • ISS (Injury Severity Score):
    • Sum of squares of highest AIS (1-6) in 3 worst regions.
    • ISS > 15: Major trauma. Max: 75.
  • RTS (Revised Trauma Score):
    • Weighted sum: GCS, SBP, RR (coded values).
    • RTS < 4: Consider trauma center.
  • TRISS: Combines ISS, RTS, Age for $P_s$ (Prob. Survival).

• Complications:

  • Early:
    • Hemorrhagic shock
    • ARDS, Fat Embolism (📌 Gurd's: 1 major + 4 minor / 2 major)
    • DIC, SIRS
  • Late:
    • MOF/MODS, Sepsis
    • VTE (DVT/PE)
    • Compartment syndrome

⭐ ISS > 15 is a key indicator for polytrauma, significantly impacting management and prognosis.

High‑Yield Points - ⚡ Biggest Takeaways

• ABCDE approach is paramount in initial polytrauma assessment and management.
• Recognize and manage the Lethal Triad: acidosis, hypothermia, coagulopathy.
• Damage Control Orthopaedics (DCO) for unstable patients; prioritize life over limb.
• Early Total Care (ETC) for stable patients, allowing definitive fracture fixation.
• Immediate pelvic stabilization (binder/sheet) for suspected pelvic ring injuries.
• FAST/eFAST aids rapid detection of internal bleeding (pericardial, pleural, peritoneal).
• Early activation of Massive Transfusion Protocol (MTP) is critical in exsanguinating hemorrhage.
